ROLLING SHUTTER.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed December 3, 1917. Serial No. 205,054.

To all whom it may concern:

Be it known that I, HENRY E. PnnLLn, a citizen of the United States, residing at the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful improvements in Rolling Shutters, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to rolling shutters and more particularly to a sheet metal shut ter formed of a sequence of interlocking, pivotally connected panels, adapted, when the shutter is opened to form a roll and when the shutter is closed to form a substantially continuous metallic barrier in the opening to be closed thereby.

The general type of shutter above re ferred to is old and well known in this art, the purpose of my invention being to pro vide a'shutter of this type wherein the elements will be excluded from the joint between the separate panels from the outside of the shutter when closed, and dust and dirt will be excluded from the joints upon the inner side of the shutter. Furthermore, a shutter made in accordance with my invention may be readily produced by a mere stamping or forming operation as to each panel, thus simplifying the manufacture of the shutters and permitting them to be economically produced. a

In the production of a shutter made in accordance with my invention, all bending operations'are avoided, the structure being such as to permit the use of forming dies, thus insuring absolute uniformity in the joints between all adjoining panels, and freedom in the operation of all joints while permitting parts of the joints to have a closer fit than would otherwise be possible.

The invention consists primarily in a rolling shutter embodying therein a sequence of panels, each panel having along one edge thereof a cylindrical hinge member, and along the other edge thereof a relatively larger cylindrical socket member adapted to receive and inclose the hinge member of the adjoining panel, said cylindrical socket member having a longitudinally extending slot therethrough through which the portion of the adjoining panel,

adjacent said hinge member, projects, said slot be1ng of a width relatively greater than the thickness of the panel to permit pivotal movement of each of said panels with relation to the adjoining panel; and in such other novel features of construction and combmation of parts as are hereinafter set forth and described and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

' Figure 1 is a front elevation of a fragmentary portion of a shutter embodying my invention;

gig. 2 is a vertical section therethrough; an

Fig. 3 is a vertical section of another em bodiment of my invention.

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, a, b and 0 indicate three panels of a shutter, each of which is of the same construction as the others, and is composed of sheet metal stock so as to make the structure sufficiently light, while fireproof.

These panels respectively have" formed along one edge thereof a cylindrical hinge member d, e or f and along the other edge thereof a substantially cylindrical socket member 9 and h adapte to receive the hinge member of the adjoining panel, said socket member having a slot extending longitudinally thereof, of sufficient width to permit relative movement of the adjoining panel to permit the rolling of the shutter when opening same, or its unrolling when closing the shutter.

To impart the desired rigidity to the shut ter when open, the major portion of this slot is disposed upon one side of the contra plane of the panel.

The panels, a, b and c are shown as being composed of two plates a/a b'?) and c-0 permanently united in any desired manner, as by means of rivets as shown, spot welding or any other desired or approved manner of uniting two metallic plates.

The plates a, b and 0 have formed along one edge thereof respectively, a half round portion (5, e or f, while the plates a 12 and 0 have a similar half round portion 6?, e or adapted, when the plates are united,

to form the cylindrical hinge members (Z, c and 7 respectively.

The other edge of the plates (t -b have formed therein, a half round longitudinally extending portion g and h, the diameter of which is relatively greater than the diameter of the portions 6 and f. The plates a and .6 each have a rounded portion and k of the same radius, but of an arc of less than 180, than the portions 9 and fa so that when the plates of eachpanelare united the portions g'g and h-h will form the slotted cylindrical socket members g and h, adapted to receive the hinge members 6 and f,the variance in the inside diameter of said socket member and the 'outside diameter of said hinge member being such as to permit a free sliding fit of these parts. 7

In the form of the invention shown in Figs. 1 and 2, the section of each panel a, 7). and 0 between the hinge member and the socket member thereof, is shown as being flat, While in the form of the invention shown in Fig. 3, this portion of each panel is shown as being formed of short fiat sections 2', y or is adjacent the hinge members, and i or j adjacent the socket members of each panel, and an intermediate outwardly curved portion 6 -j and 70 extending from the flat portions 2', j, and k to the flat portions 2" or j, the corresponding portions of the panel 0 not being shown 'in the drawings. i

The form of the invention shown in Fig. 3 has the same desirable characteristics, and mode of operation, as the form shown in Figs. 1 andQ, the curved portion 27 7' and 70 being usedmerely to permit the formation of a more compact roll, to make the shutter more decorative, and, under some circumstances, to add greater rigidity thereto.

It will beobserved that each of the panels is an exact duplicate of every other, different reference letters being used merely for the purpose of more clearly defining the op erative relation of the coacting parts of different panels. V

The operation of the herein described device is sribstzintially as follows Ashutter embodies any desired number of panels such as a, Z) an dc of any desired width according to the size of the opening tobe closed thereby. Then the shutter is open, these panels form a roll at the top, or at the bottom, of the opening as desired, the

' various cooperating hinge and socket members imparting to the shutter sufficient flexibility to permit it to take this form.

As the shutter is closed, the connected panels are draw'n'from this roll and brought into a substantially vertical line. In mounting the shutter, the hinge members (Z, 6 and f and similar hinge members will be posimaven) tioned at the top of each panel, thus causmg each of these members presented outwardly of the opening to be closed by the shutter, to be completely inclosed in the cooperating socket member which will form a shield above and about it in a manner to exclude the elements from the joint between adjoining panels.

As different panels come intothe vertical plane which they occupy when the shutter is closed, the edge of the portion 9, or the corresponding portion of each panel, will abut against the outer face of the next lower panel so as to check any tendency of the shutter to bulge while in the closed position. i

The width of the slots in the socket mem here, will permit a free relative movement of adjoining panels in opening or closing the shutter,but the portion 9 or the corresponding portions of other panels, will since the slot is presented downwardly, sufiiciently inclose the hinge member cooperating therer with, to prevent dust or dirt entering the hinge from the inside of the opening to be closed. V In the manufacture of a shutter made in accordance with my invention, each front plate is identical with every other front plate, and each back plate is identical with every other back plate, so that after these plates are united there is produced a standard panel which will'exactlyfit any other panel requiring no skilled labor in assembling as this may be accomplished by merely sliding a hinge member within a socket member axially thereof. lf, however, it be desired to assemble the structure during its course of construction, the various parts may be properly positioned before being riveted or otherwise secured together.

it is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention. I

Having described the invention what I claim as new and desire to have protected by Letters Patent is A rolling shutter embodying therein a sequence of panels, each panel comprising a front plate and a back plate, said front plate slot therein are formed, said last named member being adapted to receive the hinge member of thecadjoining panel, and said slot being of e Width relatively larger than the thickness of the panel to permit pivotal movement of each of said panels with relation to the adjoiningpanel.
